Abstract (en)

[origin: WO9846867A1] Operation of a diesel engine (10) with low particulate emissions is achieved. A diesel engine is equipped with a platinum-catalyzed particulate trap (14). The engine (10) is operated with a blend of diesel fuel and a fuel-soluble cerium composition (32) to reduce the balance point of the trap (14) with reduced cerium content. Preferably, the fuel (11) will also contain a fuel-soluble organo-platinum group metal compound (32), or an effective platinum group metal compound can be added to the exhaust or combustion air.
